September 16, 20205 yr comment_18028 I have a 686 door lining but there is a gap of 50mm from lining to internal brick wall, is this to big for foam ? Thank you in advance Report
September 17, 20205 yr comment_18039 The 50mm gap is too large for a timber-based fire door assembly. Consult 'BS 8214:2016 Timber-based fire door assemblies - Code of practice' for details about maximum gap sizes and suitable fire stopping materials. Report
